Torsion Springs

Single-Body and Double-Body Configurations

At James Spring & Wire we carefully manufacture single-bodied and double-bodied torsion springs with different end configurations including straight, offset, and hinge ends. Based on your custom application needs, torsion springs can be produced with wire diameters ranging from 0.005″ to 0.250″, and designed to rotate either counter-clockwise or clockwise. Operating environment, life expectancy, and spring load are taken into account when designing your custom springs. Our design allows torsion springs to be used in the direction that winds the coil. In general a torsion spring is used over a shaft or arbor, so when selection the appropriate mandrel size we recommend allowing roughly 10% clearance for various deflections. If your specific application requires a high deflection, a reduction in mandrel size is suggested to ensure proper performance.
